Android 微信好友分享&朋友圈分享

最近在做公司一个商城项目，涉及到了微信分享，上网找了几篇博客看了看，总结下做个无脑教程，算是自己的一个总结，不喜勿喷，有错欢迎指出。

所需材料

一份导包：

implementation 'com.tencent.mm.opensdk:wechat-sdk-android-with-mta:+'

五份权限：

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

class文件两个：

appID一个：这个需要在微信开发平台注册自己的app,具体前往这里查看

以上就是所有所需的东西，接下来开始动手把代码打上再调用就可以了

WXEntryActivity.class

这个class是

public class WXEntryActivity extends AppCompatActivity implements IWXAPIEventHandler {

    private IWXAPI api;
    private WXShare wxShare;
    String flag;
    String url;
    String title;
    String content;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.fragment_share_item);//这个布局文件随便放一个透明的就行
        flag=getIntent().getStringExtra("flag");//1:分享至朋友圈;0:分享至好友
        url=getIntent().getStringExtra("url");
        title=getIntent().getStringExtra("title");
        content=getIntent().getStringExtra("content");
        wxShare = new WXShare(this);
        wxShare.setListener(new OnResponseListener() {
            @Override
            public void onSuccess() {

            }

            @Override
            public void onCancel() {

            }

            @Override
            public void onFail(String message) {

            }
        });
        Log.e("WXEntryActivity", "WXEntryActivity");
        WXShare share = new WXShare(this);
        api = share.getApi();
        wxShare.share(flag,"这是要分享的文字");//分享文本
        if (flag.equals("0")){
            wxShare.shareUrl(0,this,url,title,content);//分享链接
        }else {
            wxShare.shareUrl(1, this, url, title, content);
        }
        //注意：
        // 第三方开发者如果使用透明界面来实现WXEntryActivity，
        // 需要判断handleIntent的返回值，如果返回值为false，
        // 则说明入参不合法未被SDK处理，应finish当前透明界面，避
        // 免外部通过传递非法参数的Intent导致停留在透明界面，
        // 引起用户的疑惑
        try {
            if (!api.handleIntent(getIntent(), this)) {
                finish();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    protected void onStart() {
        super.onStart();
        wxShare.register();
    }

    @Override
    protected void onDestroy() {
        wxShare.unregister();
        super.onDestroy();
    }

    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);
        Log.e("onNewIntent", "onNewIntent");
        setIntent(intent);
        if (!api.handleIntent(intent, this)) {
            finish();
        }
    }

    @Override
    public void onReq(BaseReq baseReq) {

    }

    @Override
    public void onResp(BaseResp baseResp) {
        Intent intent = new Intent(WXShare.ACTION_SHARE_RESPONSE);
        intent.putExtra(WXShare.EXTRA_RESULT, new Response(baseResp));
        sendBroadcast(intent);
        finish();
    }

WXshare.class

public class WXShare {
    public static final String APP_ID = "这里填你注册成功的微信appid";
    public static final String ACTION_SHARE_RESPONSE = "action_wx_share_response";
    public static final String EXTRA_RESULT = "result";

        boolean result = api.sendReq(req);
        Log.e("text shared: " + result, "");
        return this;
    }

    //flag用来判断是分享到微信好友还是分享到微信朋友圈，
    //0代表分享到微信好友，1代表分享到朋友圈
    //分享链接
    public WXShare shareUrl(int flag, Context context, String url, String title, String descroption) {

        msg.title = title;
        msg.description = descroption;
        //这块需要注意，图片的像素千万不要太大，不然的话会调不起来微信分享，
        //我在做的时候和我们这的UIMM说随便给我一张图，她给了我一张1024*1024的图片
        //当时也不知道什么原因，后来在我的机智之下换了一张像素小一点的图片好了！
        Bitmap thumb = BitmapFactory.decodeResource(context.getResources(), R.mipmap.logo);
        msg.setThumbImage(thumb);
        SendMessageToWX.Req req = new SendMessageToWX.Req();

        api.sendReq(req);
        return this;
    }

    public IWXAPI getApi() {
        return api;
    }

    public void setListener(OnResponseListener listener) {
        this.listener = listener;
    }

    private String buildTransaction(final String type) {
        return (type == null) ? String.valueOf(System.currentTimeMillis()) : type + System.currentTimeMillis();
    }
    private class ResponseReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {
            Response response = intent.getParcelableExtra(EXTRA_RESULT);
            Log.e("type: " + response.getType(),"type: " + response.getType());
            Log.e("errCode: " + response.errCode,"errCode: " + response.errCode);
            String result;
            if (listener != null) {
                if (response.errCode == BaseResp.ErrCode.ERR_OK) {
                    listener.onSuccess();
                } else if (response.errCode == BaseResp.ErrCode.ERR_USER_CANCEL) {
                    listener.onCancel();
                } else {
                    switch (response.errCode) {
                        case BaseResp.ErrCode.ERR_AUTH_DENIED:
                            result = "发送被拒绝";
                            break;
                        case BaseResp.ErrCode.ERR_UNSUPPORT:
                            result = "不支持错误";
                            break;
                        default:
                            result = "发送返回";
                            break;
                    }
                    listener.onFail(result);
                }
            }
        }
    }
}

调用

Intent intent = new Intent(getActivity(), WXEntryActivity.class);
                intent.putExtra("flag", "1");
                intent.putExtra("title","链接的标题");
                intent.putExtra("content", "链接的介绍");
                intent.putExtra("url", "你要分享的链接");
startActivity(intent);

其实就是一个简单的Activity跳转加传值

成果
